WUFI

I'm trying to model an elliptical gym in sketch up and export it to WUFIplus, but the part that should be exported as one component becomes multiple components, is there any solution to this?

Unfortunately, there are no curved surfaces in WUFI Plus. These are divided into flat surfaces. The best thing to do is to divide them manually in sketchup to avoid having too many surfaces/components in WUFI Plus which every one need some computing power
